angularjs - ui-select multiselect is very slow in displaying the choices -


i ran problem, , don't know how solve it. have used ui-select multiselect in page. first, http.get request made url gets data, ui-select choices populated. data big - length of data 2100. data shown choices. (the data fetched @ beginning during loading of page , stored in array)

but problem each time click on multiselect select choice, takes 4-5 seconds populate list , page becomes slow. do reduce time?

the choices data stored in array, datatype array of strings.

  <ui-select multiple ng-model="selectedfields.name"  style="width: 100%;">     <ui-select-match placeholder="select fields...">{{$item}}</ui-select-match>     <ui-select-choices repeat="fields in availablefields | filter:$select.search">       {{fields}}     </ui-select-choices>   </ui-select>

in controller, 

$scope.selectedfields = {}; $scope.selectedfields.name = [];  $scope.init = function() {      $http.get(url)         .success( function(response, status, headers, config) {             availablefields = response;         })         .error( function(err) {         }); };  $scope.init();

if not way, there other options/choice can work doesn't delay showing select-choices?

this known issue in ui-select. tried following ways, both work

1) there workaround - use 

| limitto: 100

this limits choice display 100 choices can selected. @ this thread more details.

2) since of time, there need display entire list in choices, 1) not viable option. used different library - selectize.js. here's plunker demo given in page
